What's the Cheapest (Legal) Way to Buy Microsoft Office?

I just bought a new computer, and with it I think it's finally time that my family and I bought the latest version of Microsoft Office. But the dealseeker in me is revolted by the idea, because it never seems like there are any good deals on Microsoft Office, the price simply is what it is.

Any suggestions on the cheapest way to go about procuring licenses for a family of three? We have one student in the family, and two teachers. I'd be much obliged for any advice!

Oh, you've got students & teachers, so you're good to go on the .edu discount. The $10 deal mentioned above is HUP - the Home Use Program. This is NOT an EDU deal, but is offered at some larger universities & corporations. Try your various email addresses to see if any qualify.
